The spec sheet matches what we know about the pocket cinema camera, and it would make sense if it was another BAE/Fairchild sensor and/or a derivative of the one used in the BMCC. Seems to make a lot more sense than the CMOSIS CMV4000 suggested here.
Most interesting to note is that both of these sensors have 6.5 μm square pixels, so low-light sensitivity should be around the same as the BMCC, and both sensors actually support global shutter at 50fps or rolling shutter at 100fps, although I don't see any reason to see these actually supported in the pocket cinema camera, due to the power and cooling requirements, especially in such a small body. But definitely interesting to think about!
Hmmm...
Kinda looks like this:

Based on the CIS2051 (which is 5.5 megapixel, so could be the BMCC sensor?)
Google CIS1021:
Found a 42 page pdf about it: http://alliedscientificpro.com/wp-conte ... t_RevA.pdfCIS1021 DATASHEET
2.1 MP HD CMOS Image Sensor
- 6.5 μm square 5T active pixels
- Diagonal 14mm (Type 1/1.2”)
- High resolution imaging array: 1920(H) x 1080(V) HDTV format
- Extra 32 dark rows (16 dark rows on top and bottom edges)
- Extra 96 dark columns (48 dark columns on left and right edges)
- Extra 16 border rows and 16 border columns enclosing the active ROI
- High speed operation: 100 fps in Rolling Shutter, 50 fps in Global Shutter mode
- Low noise: 1 e
- RMS @ 50 fps in Rolling Shutter readout mode
- High peak quantum efficiency: > 50% at 600nm
- High intra-scene dynamic range: 90dB (30000:1)
- Two 11-bit output channels per pixel via dual column amplifiers
- Column parallel 11-bit A/D conversion
- Programmable shutter modes: Rolling Shutter and Global Shutter
- Programmable Region of Interest (ROI) readout
- ROI indexed by individual row vertically and by 16-column wide blocks horizontally
- Seamless integration time change in Rolling Shutter readout mode
- On-chip temperature sensor
- Power consumption ~ 0.8 W in dual channel 100 fps operation to ~ 0.3W in single channel 50 fps operation
- Protection against black-sun image artifacts
What do you think?
